From my experience with Sense so far, it seems that the HS110 plug integration is a big plus to help with accurate device detection and reporting (and to hopefully help Sense learn in the medium term).
So I was about to buy a few more of those, and naturally went to Amazon where a new one runs $23.94 right now (at least for me, not sure if the prices are the same for everyone). Then I found that Walmart is selling them for $15.99, free 2-day shipping if you buy 3 or more.
Since I suspect many Sense users may be buying several of these, I thought I’d share.
(For the record I am not affiliated with Walmart in any way, and in fact I very rarely shop there)
